Interpol launched Operation Unmask in mid-February after a series of cyber-attacks against private and government targets.

The international police agency said that about 250 items of IT equipment and mobiles were seized during searches of 40 premises across 15 cities in Argentina, Chile, Colombia and Spain. The suspected hackers are aged 17-40.

In retaliation, Anonymous hackers attacked Interpol's website with a Distributed Denial of Service (DDoS) and briefly took it down. According to the Guardian, the site was "quickly back up and running but was loading slowly".

But a tweet by a prominent Anon called Sabu may suggest further actions by the collective against Interpol.
